MORPHOMETRIC STUDY OF RENAL VEIN AND ITS VARIATIONS USING CT

Purpose: V enous anatomy of the kidney is considered important and subjected to many variations. The commonest venous variation is presence of multiple renal veins and retroaortic left renal vein. In this study we evaluated the morphometry of renal vein and its variations. Methods: P rospective study was conducted on 100 kidney donors who underwent CT angiograms. Renal angiographic images were analysed for length, wid th of renal vein and its variations. The length was measured from hilum upto its termination and width measured near hilum of kidney and near termination. Results: The mean length of right renal vein was 3.01cm and left renal vein was 7.01cm. The mean wid th of right renal vein near termination was 1.10cm and near hilum was 1.03cm. The mean width of left renal vein near termination was 0.88cm and near hilum was0.99cm. out of 100 kidney donors the variation of renal vein was found on 23 individual. In this 1 9 had accessory renal vein and 4 individual had retroaortic left renal vein. Conclusion: Analysing CT Images demonstrated the morphometry of renal vein and its variations. Presence of these variations can be susceptible to trauma and threat to abdominal s urgical procedure especially during kidney transplantation and retroperitoneal surgery.
